It really depends what you use the car for.



Track work clutch type diffs are the best.


Road use then helical.



Clutch type diffs require rebuilding, they also require greater maintenance like oil changes every 5k miles, plus it has to be special LSD friction modifier oil.


The helical diffs are maintenance free, use no special oils, change it at normal service schedules.



Helical diff's don't work as well as clutch type because when the inside wheel becomes light, it doesn't know where to send the power and basically acts like an open diff. Obviously this is really only going to happen on the track if you're bouncing through kerbs.

Mirror what Adam has said and for the same reasons i don't like helical diffs. Drove plenty of Quaifes and they just aren't as instant to lock up like a proper clutch type diff too.

They don't clonk if you run them in properly and run the correct oil too. Always frustrates me when people say they do! They won't of ran them in or use the correct oil.

Also what you've posted up there isn't a gear set, its just a final drive, which as far as I'm aware with the TRD one shortens all the gears and lowers the top speed. depends what you want really.
